Frequently Asked Questions

Q1: What type of chassis and engine does the TR300D rotary drilling rig use?

The TR300D is mounted on an original Caterpillar 336D base chassis and is powered by a high-performance SCANIA/CAT turbocharged engine, ensuring excellent stability and load matching under variable construction environments.

Q2: What is the maximum drilling capacity of the TR300D?

It features a maximum drilling diameter of 2500 mm and a maximum drilling depth of 56 meters (interlocking Kelly bar) or 84 meters (friction Kelly bar).

Q3: How does the rotary head handle severe geological impacts during drilling?

The rotary head utilizes an advanced three-level anti-shocking technology designed to efficiently absorb kelly bar impacts, while its REXROTH or LINDE motor adapts output torque dynamically to geological conditions.

Q4: What measures are taken to prevent main winch wire rope tangling?

The TR300D implements a newly designed winch drum structure that actively prevents steel wire rope tangling, significantly extending the service life of the wire rope.

Q5: What are the main applications suited for this drilling rig?

The TR300D is ideal for drilling with telescopic friction or interlocking kelly bars, cased bore piles (driven by rotary head or casing oscillator), continuous flight auger (CFA) piles, and displacement piles for soil-mixing.

Q6: What level of control does the electronic leveling device offer?

Equipped with Pal-fin auto-control electric systems, the rig includes an electronic leveling device that monitors and automatically adjusts the mast, ensuring absolute verticality throughout construction tasks.
